recent progress in the rubber antioxidants Rubber Auxiliary Agent,various external factors, including oxidative agents (such as oxygen), heavy metals, uv rays, ozone, mechanical stress, heat, and aggressive chemicals, etc., could accelerate rubber aging. this review mainly focused on thermo-oxidative aging because it is the most common aging type for rubbers.
-6ppd is an outstanding antioxidant and antiozonant, generally used for natural rubber and synthetic rubber. -6ppd can slow rubber’s fatigue degradation under static and dynamic operating conditions. it is an excellent stabilizer for natural rubber and synthetic rubber, with low pollution and low volatility.

- Which antioxidants are used in rubber vulcanization?
- The amine and phenolic antioxidants are the most widely used rubber antioxidants (Fig. 1 b and c). Generally, the phenolic antioxidants have poor antioxidative efficiency (compared to amine antioxidants) and they can delay vulcanization, but they cause little discoloration problems.
- Is MBZ 445 a good antioxidant for EPDM?
- In the thermal-aging testing, the retention of elongation at break for the rubber sample with combined antioxidants (MBZ:445=2:1) is superior to that of other samples (Fig. 2 c), demonstrating the synergistic antioxidative effects between MBZ and 445 for EPDM.
- Can hydroxytoluene stop the autocatalytic aging reaction of rubber?
- For instance, as shown in Fig. 1 b, butylated hydroxytoluene (BHT) could donate a hydrogen atom and convert peroxy radical to hydroperoxide, and therefore it could stop the autocatalytic aging reaction of rubber by blocking the propagation of peroxy radicals (Fig. 1 b), each BHT consumes two peroxy radicals. 3.
- How to graft antioxidants on rubber filler?
- In brief, the solid-phase method to graft the antioxidant on rubber filler could reduce the use of organic solvent, and thus provide a green approach. Apart from silica, other fillers, such as graphene and halloysite nanotubes, were also widely used as a carrier to immobilize the antioxidants.
